 convert in.jpg --auto-level out.jpg

  I had to replace --auto-level by -auto-level to do that!

Hi Pablo,

you can use Script-Fu, more specifically 'gimp-levels-stretch':

This procedure allows intensity levels in the specified drawable to be
remapped according to a set of guessed parameters. It is equivalent to
clicking the Auto button in the Levels tool. This procedure is only valid
on RGB color and grayscale images. It will not operate on indexed
drawables.

You can access it in Gimp from Filters - Script-Fu - Console.

Some time ago, I published a manual about a similar procedure to
round-corners. You can consult in:

www.victorsanchez2.com/#GimpScript-FU-1
www.victorsanchez2.com/#GimpScript-FU-2

and ask me if you want.

Here you can get the script directly:

Regards,
   Víctor.

 Hi everybody:
 I use Gimp just for personal pursposes like improving the colour of my
 photos, and I have a question that I couldn´t answer by myself so far. I
 use to take the same steps with every picture when improving the colour:
 I go to menu Colors / Levels, press the button Auto, then OK, Save and
 Close file. I have 200 photos taken in a tour and I´m looking for a way
 to do this in a batch mode, for all files at once, maybe from command
 line, but I couldn´t find how in the online user manual. It seems to me
 that script-fu may be useful but the manual didn´t help me. Is there a
 way to do waht I want to do?. Can any body tell me which is the function
 or recommend me a tutorial?.
 I run Gimp 2.6 under Windows 7-64 bits
 Very much thanks in advance.

 Pablo

Some people will likely give a very documented answer for Gimp batch. But

1) there is also an auto-level in ImageMagick convert 
(www.imagemagick.org) that will likely be both faster and easier to use 
from the command line:

 convert in.jpg --auto-level out.jpg

see 
http://www.imagemagick.org/script/command-line-options.php#auto-level 
for more similar options

2) if you have to run this on all/most pictures you take, you should 
investigate changing the settings on your camera.
